SVN rev 189740 on 2009-03-12 13:45:55Z by kib
MFC r189283:
Correct types of variables used to track amount of allocated SysV shared
memory from int to size_t. Implement a workaround for current ABI not
allowing to properly save size for and report more then 2GB sized segment
of shared memory.
This makes it possible to use > 2 GB shared memory segments on 64bit
architectures. Please note the new BUGS section in shmctl(2) and
UPDATING note for limitations of this temporal solution.
MFC r189398:
Systematically use vm_size_t to specify the size of the segment for VM KPI.
Do not overload the local variable size in kern_shmat() due to vm_size_t
change.
Fix style bug by adding explicit comparision with 0.
MFC r189399:
Improve the grammar and wording in the changes to shmctl(2) manpage.
Put an UPDATING entry and bump __FreeBSD_version for the change.
